How to Answer

Discuss the definitions of ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform), emphasizing when to use each based on the data architecture and business needs.

Example

"ETL is typically used when data needs to be transformed before loading into the target system, which is common in traditional data warehouses. ELT, on the other hand, is more suited for cloud-based systems where raw data can be loaded first and transformed later, allowing for more flexibility and scalability."

2. Describe your experience with Azure services. Which services have you used for data engineering?

This question assesses your familiarity with the cloud platform that AXA utilizes.

How to Answer

Mention specific Azure services you have worked with, such as Azure Data Factory, Azure Databricks, or Azure SQL Database, and provide examples of how you used them in your projects.

Example

"I have extensively used Azure Data Factory for orchestrating data workflows and Azure Databricks for processing large datasets using Spark. In my last project, I built a data pipeline that ingested data from various sources, transformed it using Databricks, and stored it in Azure SQL Database for reporting."

3. How do you handle data migration from traditional databases to cloud environments?

This question evaluates your practical experience with data migration strategies.

How to Answer

Discuss the steps you take for data migration, including planning, execution, and validation, and mention any tools or methodologies you prefer.

4. What is your experience with data streaming technologies?

This question gauges your knowledge of real-time data processing.

How to Answer

Talk about any streaming technologies you have used, such as Apache Kafka or Azure Stream Analytics, and provide examples of how you implemented them.

Example

"I have worked with Apache Kafka to build a real-time data processing pipeline that ingests streaming data from IoT devices. This allowed us to process and analyze data in real-time, providing immediate insights for our business operations."

5. Can you explain how you would optimize a slow-running data pipeline?

This question tests your problem-solving skills and understanding of performance optimization.

How to Answer

Discuss the common bottlenecks in data pipelines and the strategies you would employ to identify and resolve them.

Example

"I would start by profiling the pipeline to identify slow stages, then look into optimizing data transformations, possibly by using partitioning or parallel processing. Additionally, I would review the resource allocation in Azure to ensure that the pipeline has sufficient capacity to handle the workload."

Project Experience

1. Describe a challenging data engineering project you worked on. What was your role?

This question allows you to showcase your hands-on experience and problem-solving abilities.
